Used a UDI U941a and just modded a tiny bit with tools. This is a fun little guy to build and fly. Great aggressive design. It was flown with various setups and weights. With all the OEM extras on board, it's quite stable for vid (best not to add the extra landing gear...too much). Most recently, I've stripped the extras, but kept the camera, and bumped to reclaimed 800mAh batts. Flies great. I'll add some pics before moving over to the v2. Haha, why not?! Anyone want to see the build? Let me know if it's worth doing in the comments.
